Czechia.

230 V · 50 Hz on Type E, Type C.

Czech sockets are Type E, the French pattern with an earth pin sticking out of the recessed wall outlet, at 230 V and 50 Hz. Two-pin europlugs and the hybrid earthed plugs found on most continental appliances fit fine. Visitors from the UK, Ireland or North America need adapters, plus a voltage check on 120 V-only devices.

The voltage window

A nominal 230 V supply may legitimately sit anywhere between 207 and 253 V (±10%). Dual-voltage gear (marked 100–240 V) shrugs at all of it.

Pack an adapter — Czechia runs 230 V 50 Hz on Type E, Type C — and your 120 V appliances need to be dual-voltage or transformed, adapter or not.
